Steady Bluebird

#235b61
Notes

Steady Bluebird (#235B61) is a deep cyan with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (186°, 47%, 26%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Steady
adjective

Old English stede, place, position — drifted to mean firm and unmoving. Used as a color modifier since the seventeenth century for hues that read as reliable rather than dramatic. Steady gray, steady green: moderate saturation combined with optical calmness. Sits in the crisp-bucket center alongside settled.

Bluebird
noun

The genus Sialia — North American bluebirds — particularly S. sialis (Eastern bluebird), whose males display saturated cobalt-blue plumage with rust-red breasts. The color refers to a male Eastern bluebird in breeding plumage: a saturated, slightly cool deep blue with the matte finish of structurally colored feathers.
